We investigate a cogenesis scenario for composite asymmetric dark matter framework: a dark sector has a similar strong dynamics to quantum chromodynamics in the standard model, and the dark-sector counterpart of baryons is the dark matter candidate. The Hawking evaporation of primordial black holes plays the role of a source of heavy scalar particles whose CP-violating decay into quarks and...
We investigate the direct detection constraint on the composite asymmetric dark matter (ADM), where the confining gauge dynamics realized in the dark sector. The dark baryonic matter is the dark matter candidate, in particular it is similar to our baryons when we assume the SU(3) dark QCD in the dark sector. In addition, the dark sector is connected to the standard model sector through the...
We did a full simulation of sensitivity reach of $U(1)_{B-L}$ gauge boson with the contribution of a light scalar. We consider a minimal extension of the standard model with a $U(1)_{B-L}$ gauge group.
Searches for primordial non-Gaussianity (NG) has the potential to not only reveal the physics of cosmic inflation, but also the structure of fundamental interactions at the highest energies. The cosmological collider (CC) physics program exemplifies this possibility and demonstrates how searches for oscillatory NG can lead to mass-spin spectroscopy of extremely heavy states. Adopting an...
